Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi,
You should first redeem the product key so it will be linked to your Microsoft account. Then, sign in with that same Microsoft account to activate Office.
You can redeem your product key here:
https://setup.office.com/redeem/enter-key
After redeeming the key, install Office and then activate it by signing in with the same Microsoft account.
- Go to https://account.microsoft.com/services
- Sign in using the Microsoft account associated with your license
- Locate Microsoft Office and click Install
- This will download the Office installer
- Run the installer and follow the on-screen instructions
Once installed, open any Office app such as Word or Excel, then sign in using the Microsoft account associated with the purchase to activate Office.
